To ALL WHoM rr Mareolvennn:V

Be it known that I, GEOitGE HILGAR, of Brownington; in the county of Butler, and State of Pennsyl- Vania, have invented Ya new and useful Improvement in Sheep-Shears; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilledA in th art to make and use the sazne,reference being had to the accompanying drawings, forming part o' this specification.

The drawing representsa face view of my improved sheep-shears.

This invention relates to a new manner of attaching and operating the third or centre tine of sheepshears,

and consists in so arranging all the partsthat` the said third 'tine can bereasily secured to sheepshears of i ordinary construction. i. e., to such that have but tiro tines, and so that the said third tine can be easily removed if desired. v .l

To one o f the arms is attached a stud, on which a lever is pivoted7 whiclrconnects the opposite arm or cutter with the inner end of the centre cutter. The latter is pivoted to that cutter from the shank of which the aforesaid stud projects.

A represents the spring of' ordinary sheep-shears, and is formed by or between" the two arms B and C oi" the same, on the ends of which the cutters Dand E are respectively formechas is clearly shown inthe drawing, and as ordinary sheep-shears are usually made. From the shank B of the cutter D projects,'not far from the junction between 'the said cutter and shank, a stud, F; towards the opposite sl1ank,being about half as long as` y the distance at that place between the two Shanks. To the end of thc stud or bar F, is pivoted, by a'pin, a, a leven G, of which one, the longer, arm is pivoted to the cutter E, near to its inner end, bymeans of a pin, b.

The other, shorter, end-of the. lever G, and the `end of the shank H, are slotted, as shown, to allow the free i .notion of all the parts, and to allow the di'erence of the dist-ance between the pins b and c and the-pine, which` is occasioned by the rotation of the lever around its pivot a, Whilethe points b and c turnr'on `altogether different centres. The cutter I is held between the cuter cutters D and E, and thepoints will always be in the centre, or equally apart from the points of D and E. .i

Old shears can be easily converted into three-titled shears by means of my invention, andthe centre tine can be easily removed by springing the ends of the lever Goff the pins band c, and by removing the pin d.

What I claimas new, and desire to secure by Letters Patent,`is

The manner herein shown and described of attaching the central cutter I to and connecting it with the ordinary cutters D and E, by means of the pin d, lever G, and stud F, or its equivalent, all made as set forth.
